TREE-NOTCIING DEVICE.

Application filed April 20, 1925. Serial No. 24,401.

The present invention relates to a sawing device and has for its object to provide a device of this character which embodies novel features of construction, whereby a wedge shaped block can be cut out from a piece of wood by the action of two saw blades which are arranged at an angle to each other.

Further objects of the invention are to provide a saw device of this character which is comparatively simple and inexpensive in its construction, which can be easily manipulated, and which can be used for yforming a notch in the base of a tree trunk preparatory to felling the tree. y

vThe invention also contemplates the provision of a novel form of saw handle which can be applied to the main saw blade with the handle either in the plane'of the saw blade or at right angles thereto, depending upon the particular mounting which is inost advantageous for the kind of work to be performed. y

One particular embodiment of the invention is shown and described in this application for illustrative purposes, although it will be understood that many modifications and changes can be made in the details of construction without departing from the spirit of the. invention.

For a full understanding of the invention reference is to be'had to the'following description vand accompanying drawings in which, Y

Figure 9 is a detail view of the clamping plate which cooperates with the nut to engage the main saw blade.

Corresponding and like parts are referred to in the following description and vindicated on all of the views of the drawing by like reference characters.' f'

Referring to the drawings, thej numeral l designates a threaded stem which has a tubular handle 2 fitted thereon, a stein and handle being adapted to be applied to each end of the saw blade so that the latter can be handled and manipulated in the saine manner as the well known cross cut saw. The threaded stem 1 is formed with a longitudinal slot 3 which may receive the saw blade 4 when the same is fastened in posieoV tion in the plane of the handle, as shown Y,

by Figure 2. W'hen the handles are applied to opposite ends of the saw blade in this manner the saw can be manipula-ted in the same manner as an ordinary cross cut saw, although when notching or cutting a. tree trunk it is preferable to secure the handle to the saw blade at right angles to the latter. as shown by Figure l, since with this arrangement it is possible to cut the tree closer to the ground and there is less wastage in the form of a stump.

With the arrangement shown by Figure l the saw blade 4 is clamped between an upper disc 5 which is threaded upon the stem 1, and a lower disc or clamping plate 6 which has a large central opening 7 yto receive the end of the stein l and is connected to the disc 5 by means of the screws 8. The saw blade is provided at the end thereof with suitable openings to receive the steml and screws 8. The disc has a threaded engagement with the stem and can be adjusted to any desired position in the length thereof, and when the screws 8 are tightened the saw blade is `securely clamped betweenthe disc 5 and the clamping plate ordisc 6. y

The auxiliary rsaw blade 9 is arranged abovethe main saw blade 4 and arranged in an angular relation thereto. vThe end of the auxiliary saw 'blade 9 is engaged by a clamp 1.0, which is hingedly connected at l1 to a. cellar l12, said collar being slidable upon a sleeve 13. clampingscrew lla at the hinge connection ll enables the auxiliary saw to be adjusted and Set at any desired angle, depending upon the depth or" the notch which it is desired to Vcut in the side of the tree trunk.

The sleeve 13 is threaded upon the stem l, and can be adjusted up and down thereon to any desired position. nut lllis threaded upon the lower end et the sleere, and a iam nut let may be threaded upon the stem l and caused to engage the lower end oit the sleeve for locking the sleeve in an adjusted position. rl`he collar l2 normally engages a shoulder l5 in the. upper end' et the sleeve, and a coil spring l5 which surrounds the lower end et the sleeve is interposed etween the collar l2 and the nut lli. This spring normally tends to slide the collar upwardly and he dit against the shoulder l5, although the collar is mounted so that it can slide downwardly upon the sleeve against the action of the spring,l 16.

lWhen the device is used :tor sawing; a notch in the side` of a tree trunk, as shown by Figure l, the auxiliary blade 9 is set and lirmly clamped at the desired annle to the main saw blade fl. VThe two saw blades will then bite their way simultaneously into the tree trunk as the device is'reciprocated baclr and forth in the usual way. As the auxiliary saw 9 enters the tree trunk the inclined cut made thereby tends to move it downwardly toward the main saw l, although the auxiliary saw moves in a direction parallel to itself, so that it always has the saine angular relation to the main saw blade. The inclined cut produced by the auxiliary saw 9 will eventually intersect the cut produced by the main saw at, with the result that a wedge shaped bloclifwill be cut out 'trom the tree trunk. rThis results in notching` the tree trunk in substantially the saine manner that tree trunks are ordinarily notched with an ax, and the use. ot this 'sa-w device. not only facilitates the 'formation of the notch, but also enables the notch to, be formed close to the ground so that there will be very littleot the tree trunk remaining' in the stump.

1When the` main saw blade l is secured to the handle in the plane thereof, shown by Figure. 2, a washer or plate l? with a transverse groove in the lower face thereof is i`ntefrposed between the lower end of thetubular handle member 2 and the upper edge of the saw blade,- the said upper edge et' the saw blade being,` received within the'A groove. of the washer member. i The lower edge of the saw blade may be engaged the lerfs or tc'lies in the upper ends of the sere-vis 8.
